PS3 Project RSX Boost: Overclock your Retail PS3 RSX Speeds (ps3 cfw only)

[batuervan]

Here is the @JoeSapecudo's one, also a Latin American model but from Brazil.

Confirmed that running the CECH-2511A at 850/750 MHz presents no issues.

The FPS dropped from 59 to 54 in GOW Ascention compared to 800/1000, as i already stated the Memory clocks also gives a FPS boost.

850/1000 will show the real result.

@Charles_n_town can you make 850/800 up to 1000 and then a test 900/700?

I think it's better to test increments of 50Mhz each time.

I have two PS3 slims, both with JTP code and JSD code. It is stated on the label that your console is a PS3 produced by FOXCONN (FOX). I'm asking so I can make a comparison. Are FOXCONN (FOX) manufactured components better for overclocking or Maintek (MTK) manufactured components? Finally, is your console JTP or JSD?

 

[Charles_n_town]

Sorry to bother you, would it be possible to get some of these made with a 650mhz core and then 800mhz vram with 50mhz increments up to 1000mhz just so I can do some testing with one of my consoles? I do have a hardware flasher hooked up to my console as a backup but at 700mhz core it became unstable.

Sure.

Make sure you have your flasher on hand in case it's too much for your system to handle.

 

[Joonie]

Yeap, see here at 8:38

I don't know if that video logging can be enabled on regular DEX OFW or it needs a specific module created for dtcpipfw only.

@zecoxao or @mysis should know more about it.

@LuanTeles my ps3 does 850/950 fully stable. 2501B. its incredible. now i wonder if 900 is possible.

 

[Nascar1243]

Sure.

Much appreciated, I have a full dump of it and do have a flasher on hand.

How do you dump this?

 

[Nascar1243]

How do you dump this?

I got a full dump using a Teensy that was soldered to the board, I made backups of this dump too as well just in case.

Hello, guys. How can I get from which model i have rsx? I have cecha00 with frankie mod. Unfirtunately I don't know rsx revision. Is it posible to get this info by evilnat? At the moment I have default OC. It looks stable (crysis, black flag, gow: ascension)

 

[LuanTeles]

@RIP-Felix 2501B Manufacture date December 2010. 900/950

Try crysis on it

 

[cha0shacker]

Can it run Crysis?

 

[Tanzu15]

Try crysis on it

I did. It's stable.

Can it run Crysis?

Yes. Lol stable too. Tried crysis 3 too. Stable. And I've been playing for hours. Across a bunch of games.

Yes, use evilnat CFW tools to dump lvl1 to a USB device. Open it on a PC with HxD. Search for your clocks. For example, if you the default OC of "600/750" search for that. It should take you directly to the info I'm referring to. Post post everything from rsx to the end of the 3 bracked sections. That contains the rsx info about fab and VIDbin.

Hi everyone, I've signed up so I can post my results trying this amazing project.

My CECH-2003A (65nm RSX) is stable at 700/900.

750 GPU produced artifacts even on the XMB, but 700 is completely stable. 950 VRAM seemed stable at first, so I tried 1000 but that caused the XMB to consistently crash on the XMB after 20 seconds. Going back to 950 it was completely stable during 10+ hours of demanding gameplay (Far Cry 3, Crysis, GT6), but it would occasionally crash when rebooting or exiting a game, so I took it down to 900 where I've had no problems since.

A 45% (average) improvement, completely stable - wow. It does make me wonder why Sony didn't clock the slim models higher themselves, because they probably all can manage 600/700 at least.

 

[ryeno]

I've gone up to 700/800 on my CECH-2504A with datecode 0C and it seems completely stable though I'm not sure if going further is worth the risk considering I've wanted NFS Carbon to run at 60fps and it's still nowhere near it (around 40fps ingame)

Assassins Creed 1 I think did not improve at all, I guess it's purely bad programming / CPU bottleneck.

The darkness on the other hand is completely fixed now with the overlcock, no 15 fps lock like on a non-OC console

try 750/750 and 700/900

I noticed the same issue on one of my systems. 950 was game stable but would crash when starting the game.

The early RAM was only rated at 677 but later RAM was rated 700. So all Slims should be able to run 700 RAM. I think Sony kept the clocks the same to ensure hardware compatibility.

 

[Mitsu™]

I hadn't tried Crysis yet !
On my CECH-2004B at 700Mhz/800MHz, no artifacts at all, 30fps with some rare, slight drops.
Not bad for this model

Wow, so 900MHz VRAM is possible on 20XX slims ? I wouldn't have bet on this !
I impressed by both your bravery and your PS3

Actually later slims can do 1000. One of mine can do 1000 on memory but only 700 on core. Though it seems memory does have big FPS gains.

This is a slim right? I believe they are a 2009 slim?

 

[Mitsu™]

This is a slim right? I believe they are a 2009 slim?

Yes, a 65nm RSX slim with "9C" for date code (the third quarter of 2009 if you prefer). The 20XX series.

1000MHz on a slim with a 65nm RSX ?

 

[Hevy007]

Sure.

Hi Charles,
Please sir, 700/800, 700/850 and 750/800. Thanks a tonne.
Trying it on my A01 franky 65nm.

It's reassuring to know you also had that issue, at first I thought it was a bug with the beta firmware. I guess keeping hardware compatibility was the safe option, but it might have been nice to have a PS4 Pro-like boost mode. Would have been a good selling point I imagine.

Oh, I absolutely took baby steps testing! Started at 700 and worked my way up by 50, testing for at least an hour each time. Bear in mind too that although 950 VRAM seemed very stable ingame, it was causing issues on reboots and starting/exiting games, so look out for things like that if you're thinking of testing further.
